Claims.

My invention relates in general to means for treating articles, such as clothing, bedding, furs, woolens, and the like, and in particular to means by which such articles can be subjected to gases,

5 vapors, or particles of a volatile substance for the purpose of fumigating, disinfecting, exterminating moths, or rendering articles moth-proof.

Those skilled in the art are aware of the fact that the extermination of insect life either in the fully developed form or in the larva stage is made most effective when the exterminating agent is under a pressure abovethat of the atmosphere.

In United States Patent No. 1,817,532, issued to me on August 4, 1931, I show a similarmeans.

In this patent, as well as in the present invention, the opening through which the articles to be treated are inserted is closed by means of a hookless fastener. As is well known, such fasteners provide numerous minute openings through which any air under pressure contained within the device will escape.

The object of my present invention is to provide means located on the inside of the receptacle and over the hookless fastener which shall be pressed against the same when the receptacle is under air pressure and which will substantially seal the openings of the fastener against leakage of air and vapor. I v

Another object has been to provide such means which shall not interfere with the placing of articles within the receptacle nor the actuation of the hookless fastener in opening or closing the container. Moreover, my invention is automatic in its action and depends solely upon the pressure of the air within the receptacle.

The above objects and advantages have been accomplished by the device shown in the accompanying drawings, of which:

Fig. 1 is a perspective view, showing one form of my invention. V

Fig. 2 is a sectional, plan viewthereof, taken on line 2--2 of Fig. 1. V

Fig. 3 is a perspective view of a modified form of invention. I

Fig. 4 is a longitudinal, sectional elevation the same, and is taken on line 44 of Fig. 3.

Fig. 5 is a transverse, sectional view of the form of device shown in Fig. 3, and is taken on line 55 of Fig. 4.

Fig. 6 is an enlarged, fragmentary view of the inside of the form of device of Fig; 3. v

Referring now to the form of invention shown in Figs. 1 and 2 a receptacle 10 is provided which .55 is preferably made of flexible or collapsible ma- 1932, Serial No. 636,519

terial which is of a non-porous nature, such, for instance, as rubberized cloth. The device comprises a top 11 and bottom 12 which may be of rigid material. The side Walls 13 are connected to the top and bottom by stitching which is preferably made airtight.

In one of the side walls of the receptacle there is arranged a longitudinal opening 15 which extends from a point near the top of the container to a point somewhere below the center thereof and which is of such a size that articles to be treated may be conveniently placed therethrough. This opening is preferably closed by a hookless fastener 16. Arranged at some distance below the bottom of the opening 15 is the inlet opening .17 of the device which preferably comprises a tube 18 secured to the side wall by means of a flange 19 and suitable rivets or screws 20. The device is provided with a hook 21 which is attached to an eyebolt 22 passing through an eyelet 23 and into the top 11, thus providing means for supporting the entire device.

Arranged opposite the side wall having the opening 15 is a curtain 25. This curtain is located on the inside of the container and is stitched at 26 to the top of the side wall and at 2'7 to the bottom thereof. At 28 the curtain is stitched along its longitudinal edge to the side wall. The front edge 29 thereof is loose and free to move back and forth when placing articles within the receptacle and when they are being subjected to treatment. This curtain may be of the same material as that of the bag and is impervious to the passage of air. This curtain, because it extends to thebottom of the side wall of the receptacle, also extends over the inlet opening 17. By extending over this opening, it will be impossible to withdraw air from the receptacle by suction for the reason that the curtain would be drawn toward and into contact with the inner end of the opening and close off the same. When my device is used with the household vacuum cleaner for which it is especially designed, such arrangement of the curtain prevents accidental operation of the suction side of the cleaner upon the receptacle, and the consequent withdrawal of any vapors which may be within the container, and makes it absolutely necessary, if results are to be obtained, that the pressure side of the vacuum cleaner be utilized. Obviously, when pressure is to be created within the receptacle, the portion of the curtain lying in front of the inlet opening will be blown away from the side wall and thereby permit air under the pressure produced by the vacuum cleaner to be forced into the receptacle.

In the form of invention shown in Figs. 3-6, inclusive, the receptacle 35 is provided with flexible side walls 36 which are connected toa top 37 and a bottom 38. A rigid member 39 either in the form of a piece of pressboard or the like, or a wire frame may be arranged under the top 37, whereby the top of the receptacle may be made rigid and thus provide convenient means to which to attach an eyebolt 22 and a supporting hook 21. The eyebolt may be passed through an eyelet 23, as in the form shown in Fig. 1. If desired, a rigid piece 41 may also be provided at the bottom 38 of the receptacle to give form to the receptacle and to provide a support upon which articles to be treated may be placed. In one of the side walls of this receptacle is also provided a longitudinal opening 42 which is closed by a hookless fastener'43. A tube 44 providing the air inlet opening is secured in the same side wall as that having the opening 42 and preferably near the bottom of the receptacle and below the last'mentioned opening.

The tube 44 may be connected to the fabric in.

any suitable manner, as, for instance, that described in connection with the form of invention of Fig. 1. As shown in Fig. 4 a container 45 is located on the inside of the receptacle and is in communication with the opening in the tube 44. This container, like those shown in the hereinbefore mentioned Patent No. 1,817,532, is perforated and provides means for holding a crystallized insecticide, and it may be removed if desired.

In this form of my invention a curtain 46 is provided on the interior of the receptacle and is located adjacent the side wall of the receptacle which has the opening 42. This curtain extends only to a point between the air inlet tube 44 and the bottom of the opening 42 and has its lower end 47 stitched to the side wall. The two side edges 48 are, however, free and unattached, and the upper end of the curtain is secured to a bar 49. This bar extends across the opening onthe inside of the receptacle and is secured to the inner part 50 of the operating member 51 of'the hcokless fastener. It is obvious, therefore, that as the member 51 of the hookless fastener is manipulated to open or close the opening 42-, the upper end of the curtain 46 will be moved up and down therewith. In Fig. 4 the fastener 43 is shown in its fully closed position and the curtain is in its operative position. Also in this figure in dotted lines is shown the fastener in its fully opened position and the curtain resting on the bottom 38 of the receptacle. By attaching the curtain to the receptacle only at its lower end and attaching it at its upperend to the member 50 of the fastener, it will be entirely out of the way when the opening 42 is being used to place articles within the receptacle to be treated or when removing them from the receptacle. When, however, articles have been placed withinthe receptacle and the opening 42 closed by raising the member 51 of the hookless fastener, the curtain will be automatically moved to its operative position and in such position will be forced against the inside surface of the fastener when pressure is applied through the tube 44 to the interior of the receptacle. Any suitable means, other than those shown, may be employed in either form of device for permeating the air within the receptacle with insecticide, and such means may be placed within the receptacle or suitably arranged in the passageways carrying air-to it.

Furthermore, it is prefer- I a rubber sleeve over the bolt and through the eyelet. In the present invention I have shown and described the article opening as being closed by means of hookless fastening means, but it is obvious, that any suitable fastening means may be employed, as, for instance, hooks and eyes, snap fasteners, or buttons and the like. These and other modifications of the details herein shown and described may be made without departing from the spirit of my invention or the scope of the appended claims, and I do not, therefore, wish to be limited to the exact embodiment herein shown and described, the form shown being merely a preferred embodiment thereof.

Having thus described my invention, what I claimisz. p
